>In case you need a guide, here are some general dancefloor sizes based on the apporximate number of guests dancing at any given point:

12′ x 12′ : 32 people or 144 square feet
12′ x 20′ : 52 people or 240 square feet
16′ x 16′ : 56 people or 256 square feet
18′ x 18′ : 72 people or 324 square feet
16′ x 24′ : 85 people or 384 square feet
20′ x 20′ : 88 people or 400 square feet
16′ x 28′ : 100 people or 448 square feet
18′ x 26′ : 104 people or 468 square feet
24′ x 24′ : 128 people or 576 square feet
26′ x 26′ : 150 people or 676 square feet
20′ x 40′ : 178 people or 800 square feet
30′ x 30′ : 200 people or 900 square feet
36′ x 36′ : 288 people or 1,296 square feet
40′ x 40′ : 355 people or 1,600 square feet

***REMEMBER! The best way to calculate how many square feet you will need is take the total number of guests, divide by 2 (because only 1/2 the people will dance at one time), and multiply by 4.5 square feet per person. This gives you the approximate square footage you will need for dancing, and then use this chart to pick the dimensions closest to that number.

Example: 200 guests/2 = 100 people * 4.5 sq ft = 450 sq ft.
